Good luck running this on a potato
After zhuzhing upPortalwith ashiny RTX version last year, Nvidia is at it again.
This time, its ray-traced the cube-shaped edges ofPortal: Prelude, the fan-made mod that serves as a full-length prequel to Valves beloved puzzler.
you could go and download Portal: Prelude RTX for free now, as long as youve got the hardware to run it.
Like Portal RTX, Portal: Prelude RTX was remastered using Nvidias RTX Remix tech, which up-rezzed the popular 2008 mods textures while adding support for ray-traced lighting and reflections.
The RTX release additionally upscales the original mod to DLSS 3 - which aims to counteract the performance hit of tracing all those rays by rendering extra frames, presumably keeping things smooth as a Portal turrets shiny exterior.
Also included in the list of acronyms is RTX IO, which aims to minimise texture load times by offloading CPU work to an RTX GPU, asKatharine handily explains here.
If youre not familiar with Portal: Prelude, the mod includes 19 new chambers in the style of the seminalpuzzle game, and follows new character Abby in an origin story for both Aperture Science and GlaDOS.
As far as mods go, its an impressive creation, featuring full voice acting and a campaign lasting around six hours or so.
Like the RTX overhaul for Portal, Portal: Prelude RTX will require you to have agraphics cardable to handle all that ray-tracing goodness, with the mods specs listing a RTX 2060 as the baseline and recommending an RTX 3080 - lower than the original Portals 3060 minimum.
Even so, your mileage may vary if the mods Mixed reviews on Steam are anything to go by, with even those running at least the minimum spec running into some performance troubles - although it seems that more criticism is directed at the mods puzzle design than its framerate.
Still,it wont cost you a penny to give it a go, as long as you already own Portal.
